My invention relates to apparatus for cool in liquids delivered fromtaps, faucets, or drinking fountains and the object of the invention ingeneral is to provide a cooling coil of eificient design andconstruction which may be used advantageously within a small tank orcompartment in connection with a refrigerating unit of standardconstruction.

In the accompanying drawing, Fig. 1 is a perspective view of a drinkingfountain cabinet containing my improved cooling ap paratus, and Fig. 2is a top view of the same cabinet, on a larger scale, with the cover ortop removed. Fig.3 is a vertical sectional 1 view longitudinally throughthe upper part of the cabinet on line 3- 3 of Fig. 2. Fig. 4 is avertical sectional view transversely of the cabinet on line 4-4 of Fig.3. Fig. 5 is an enlarged sectional view yertically of the- 2 upper. endof one of the end manifolds of the cooling coil.

As shown in the drawings, the invention has been applied to adrinkingfountain cabinet 1 havin a removable top orcover 2. An overflow owl 3 ontop 2 contains a jet, bubbler or other device 4 adapted to deliver astream of drinking water at an inclination, or perpendicularly, into thebowl. A valve 5 is used in the present apparatus to control thedischargeof water from jet 4. A cooling coil 6 made of copper pipeisconnected to the body of valve 5, and this coil is confined-within arectangular receptacle or tank 7 which is lined upon its outside withcork or other insulating nfaterial 8. A refrigerating unit 9 is mountedupon one end wall of the tank,

and the supporting head 10 of this unit is provided with circulatingpipe connections ,11 for the refrigerating medium of whatever kind ornature used. The cylindrical body of unit 9 extends horizontally intothe upper part of tank 7, and loops 12 for the refrigerant depend fromthe body toward and into the. bottom of the tank, the whole unit beingusually submerged within a body of water I maintained within the tank atauniform level by an overflow pipe 13. A cooling apparatus of thatgeneraltype is not broadly new, but in order to obtain efficient coolingeffects anda relatively large storage capacity top,

' lowing the sides of a supply of drinking water within a smallercabinet than that used heretofore, I have devised a new and usefulcooling coil 6 which is of U -shape when viewed from the whereby bothsides and the inner end of the refrigerating unit 9 are flanked andenclosed by the coil, although spaced apart therefrom. The coil is madeof separate sections of pipe, each of which is bent into loop orU-shape, and these sections of pipe are superposed andtheir open ends orextremities 15 welded to hollow upright members or manifolds 1616. Twosuch manifolds are used each having a series of reverted or return bendchannels 17; and the ends of the I pipes are connected to the manifoldsin such a manner that the several pipe sectionsprovide a singlecontinuous passage from a supply pipe 18 to a discharge pipe 19. Thus, spp y of manifold 16, and the water passes therefrom into one end of thetop or highest pipe section and thence through said section (folandacross one end of the tank) to the top of the second manifold 16,

and thence downwardly through the first reverted channel 17 to theintake end of the next pipe section immediately below the top section.The water now passes through this pipe section back to the first-manifold 16 I and thence downwardly through a reverted or return bendchannel in this manifold to the next lower pipe section, and so oncircuitously through all the remaining pipe sections and return bendsuntil the water passes from'the bottom of the first manifold 16 intothebottom pipe section 14-which has its outlet end or discharge portion19 bent upwardly to permit a connection to be made with the valve 5instead ofwith the second manifold 16. The refrigerating unit and thecooling coil are both submerged in water or other. suitable solution inthe tank, and

cooling of the drinking water in coil 6 is effected. by maintaining thewater in the tank at arelatively low temperature. T

A cooling coil constructed as delineated has a relatively large storageand cooling capacity; it permits a smaller tank and cabinet to be usedthan heretoforefit takes up pipe 18 connects with the upper end 70 i v1,77o,e7s

only a narrow space within the tank; it parallels three sides of thetank and spans the inner end of the refrigerator unit; it permits easyassembly of the parts within the tank; it ma be made of short'pieces ofpipe the mani olds may be cast; and the cost of the entire outfit,lSCOIlSidGIfiblY reduced compared with prior structures and practices,while the cooling efliciency is greatly increased.

What I claim, is: P 1. A cooling apparatus, comprising a cabinetcontaining a water tank,a water-distributing fixture mounted upon saidcabinet, .a refrigerating unit extending into said tank,

an overflow pipe for said tank, a water cooling and circulating coil ofsuperposed loop shaped pipe sections extending along one side of saidtank and thence across one end and back along the other side, a supplypipe connection for the upper pipe section, and a discharge piconnection for the bottom section and sai water-distributing fixture.

2. A cooling apparatus, comprising a water tank, a water-distributingfixture, a refrigerating unit extendin into said tank, a watercirculating coil 0 superposed loop shaped pipe sections extending alongone side of said tank and'thence across one end and so back along theother side, a supplypipe connection for said-coil and a discharge pip'econnection for saidcoil and said water distributing fixture.

3. A coolin apparatus, comprising a reas ceptacle, a re igerating'unit'extending into a said receptacle, a series of superposed U- -sha d pipesection enclosing the free end of saidfefrigera'ting unit and connectedin series at their corresponding ends, to form a con- 40 tinuous coil, asuppl pipe connection-for one end-of said coil an a discharge connectionfor the other end of said coil.

4. A coolin apparatus, comprising a receptacle, a re igerating unitextending into 15 said receptacle, a series of superposed pipe sectionsloosely fitted into said receptacle and enclosing the extending portionof said refrigerating unit, said pipe sections having open ends, spacedapart from each other,

00 means to connectsuperposed open ends of adjoining'sections to form acontinuous coil,

. and supply and discharge connections for said co f In testimonywhereof I aflix my sifiiature.
